What I'm asked about the Zenith El Primero 03.2091.410/01.C494

What strap size does the Zenith El Primero 03.2091.410/01.C494 take?

For this reference I won't give you a size I'm not sure of yet. Send me a photo of the watch on WhatsApp: I'll recognise it and tell you how many millimetres you need.

Can the strap on the Zenith El Primero 03.2091.410/01.C494 be changed?

Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.

It is equipped with the El Primero 410 caliber featuring column-wheel chronograph, small seconds, full calendar, and moon phase indication. The reference 03.2091.410/01.C494 has a movement beating at 36,000 vibrations per hour for high chronometric precision.
